Seeing as Stephen King’s Under The Dome has an entire dome-town full of characters, we could conceivably spend every hour hence tracking casting announcements for the CBS series version, increasingly trapped beneath that burden with a sea of people clamoring for their own personal space, in some kind of metaphor for something. But instead we’ll just focus on Dean Norris, whose casting as the trapped city’s Big Jim—local car dealer, minor politician, and eventually ruthless dictator—is especially notable, both because of the importance of the role and because Norris is on Breaking Bad, which is an excellent show that’s ending, unfortunately.
